Email me about wrong results, new tool ideas, or partnership proposals.

I usually reply within 1–3 business days.

Before you write

  • Bug reports — which tool, which inputs, what result you got. A share URL helps me reproduce fast.
  • Tool requests — common requests get prioritized. One or two lines on the use case.
  • Result accuracy — if a KEC/KS/code table citation looks off, send the source and I'll verify and update.
